4200 running using MegaSquirt on COP and GM sensor - 03/08/09 09:58 PM
Well the engines running using the GM crank sensor triggering the MS box running MS extra code. The MS is running the stock COP ignition coils in wasted spark mode.
This is a big jump forward in allowing folks to swap in this motor with out paying a fortune to get the GM electronics tweaked.
In time the software will come to run the VVT.
The only modification required now is to convert to a cable type throttle body. Any one with access to a mill can do this easily in 4 hours.
Cost of a good used 4200 about $600, cost of a prebuilt megasquirt to run the motor $400. Used laptop about $100 if you don't have one. Cost of a used LS1 throttle body $50. So for under $1200 you have a running 4200. Less than $4.50/hp for a 275 hp engine.
Just for giggles some hotrod parts prices for the 250/292....
Cost of an edlebrock carb about $300. Offy intake $280. Header from clifford $390. <<< already at $970 add a cam and lump ports, head work << easy $500. $1500 for maybe 225 HP. Prices are from summit racing for new parts.
I'll post a video later tonight.
